Cytotoxic and Phytotoxic Activities of Native Brazilian Forest Gabiroba ( Berg.), Fruits, and Flour against Shrimp ( L.) and Lettuce ( L.).

Gabiroba, a native fruit in Brazil's Atlantic Forest region, has significant nutritional and therapeutic properties. However, due to its seasonality, consumption by the population is limited. Thus, the development of gabiroba byproducts would add significant value to the food and therapeutic industries.

RNA-dependent RNA polymerase (RdRp) natural antiviral inhibitors: a review.

Viral diseases are the cause of many global epidemics, leading to deaths, affecting the quality of life of populations, and impairing public health. The limitations in the treatment of viral diseases and the constant resistance to conventional antiviral treatments encourage researchers to discover new compounds. In this perspective, this literature review presents isolated molecules and extracts of natural products capable of inhibiting the activity of the nonstructural protein that acts as the RNA-dependent RNA polymerase.

Microscopic investigations of Ocotea paranaensis-A Brazilian endemic and endangered species.

This article describes the morpho-anatomies of the leaves and stems of Ocotea paranaensis Brotto, Baitello, Cervi & Santos (Lauraceae) using light and scanning electron microscopy. The main anatomical features characterizing the species are the presence of simple non-glandular trichomes in the leaves and stems, large secretory cells in the leaves, flat-convex petioles with two small lateral ribs, brachysclereids in the stem cortex and pith, and the presence of starch grains and various types of calcium oxalate crystals in the pith. Histochemical tests indicated the presence of lignin in stone cells, fibers, and xylem.

The aim of this study was to investigate the chemical composition, mineral content and report the effect of gastrointestinal digestion on the proteins, phenolics, flavonoids and antioxidant activity of morphological parts of Amaranthus viridis (AV). The macronutrients found in the greatest quantity were proteins (leave, inflorescence and seeds) and fiber (roots and stem). The main minerals were calcium, potassium, iron and zinc.

Mineral Content, Antioxidant Activity and Essential Oil of Allophylus edulis (A. St.-Hil., A. Juss. & Cambess.) Radlk. Leaves: Plant from South American Biodiversity.

Allophylus edulis (A. St.-Hil.

(Nees) Mez: structural elucidation of C-hetorosides flavonoids and evaluation of their antioxidant and antibacterial properties from ethyl acetate extract.

The genus exhibits a variety of pharmacological, antibacterial and antioxidant effects. The aim of the present study was to evaluate the antioxidant potential and antibacterial properties of the ethyl acetate fraction of leaves. Isolation and identification of the phenolic compounds from the fraction was also carried out.

Preliminary evaluation of the larvicidal activity of extracts and fractions from Ocotea nutans (Nees) Mez against Aedes aegypti.

Introduction: Aedes aegypti is the main vector of dengue and yellow fever. Recently, the use of plant-sourced larvicides has gained momentum.

Methods: The hydroethanolic extracts and fractions ofOcotea nutansleaves and stems were bioassayed to determine the larvicidal efficacy of these samples.

Effect of watercress extract supplementation on lipid profile and oxidative stress markers in overweight people with physical disability: A randomized, double-blind, and placebo-controlled trial.

Studies have demonstrated that diet rich in cruciferous vegetables of the Brassicaceae family can reduce the risk of cardiovascular diseases and oxidative stress levels. Nasturtium officinale (Brassicaceae), commonly known as watercress is a perennial dicotyledonous plant usually found close to water. Although previous investigations have demonstrated the beneficial effects of watercress on hypercholesterolemia in animal studies, until now no such studies have been conducted with humans, up to this time.

Characterization and identification of chemical constituents of Brotto, Baitello, Cervi, & E.P. Santos and their biological properties.

The growing interest in the discovery of new compounds from medicinal plants justifies the study of phytochemical components of these plants and their biological activities. The genus exhibits a variety of pharmacological, antimicrobial and antioxidant effects. The aim of the present study was to evaluate the antioxidant potential and antimicrobial properties of the ethyl acetate fraction of leaves.

: antifungal activity and structural elucidation of ellagic and 3-O-methyl ellagic acids.

Natural products, especially plants, have been investigated as sources of new substances with antimicrobial properties. In this context, the genus is extensively researched for presenting such activities. This work aims to evaluate the antifungal, antibacterial, and antioxidant properties of extracts and fractions of stems of , also to characterize two phenolic compounds.

Biomarkers of oxidative stress and inflammation in people witha physical disability treated with a standardized extract of Nasturtium officinale: A randomized, double-blind, and placebo-controlled trial.

It is well established that plants from the Brassicaceae family, particularly watercress, have been associated to reduce oxidative DNA damage. Nasturtium officinale R. Br (watercress) contains glucosinolates, with anti-inflammatory action and protective effect on human health against oxidative stress.

Chemical composition of the volatile oil of Linnaeus and its allelopathic activity.

Several essential oils have allelochemicals with phytotoxic effects. species are producers of secondary metabolites with biological potential. In the present study, chemical composition of the essential oil extracted from aerial parts of Linnaeus was evaluated by gas chromatography and the phytotoxicity of the oil on seeds was evaluated for the first time.

Development of W/O/W emulsion with gallic acid in the internal aqueous phase.

The aim of this work is to develop a W/O/W multiple emulsion with gallic acid in the internal aqueous phase (W). A quantification method for gallic acid using HPLC-UV was developed and validated. In the first step, a simple W/O emulsion was prepared with distilled water, polyglycerol polyricinoleate, sodium chloride, gallic acid and pH 5.
